For Magnetic Resonance Imaging (MRI) applications, it can be important to collect auxiliary physiological data in conjunction with the Nuclear Magnetic Resonance (NMR) image data. This auxiliary data includes physiological signals such as: Electrocardiogram (ECG), Electromyogram (EMG), Electroculogram (EOG), Electrogastrogram (EGG), Temperature, Respiration, Eccrine Activity (EDA, EDR, SCL, SCR or GSR), Blood Volume Pulse (PPG), Hand Grip Strength (Dynamometry), Finger Twitch, and a variety of pressure based signals.
This application note addresses some of the practical concerns associated with collecting physiological data during the MRI scanning process. Practical concerns relate to the ability to collect such data while maintaining:
A safe environment for the subject.
High quality NMR image data.
IMPORTANT!See Safety Guidelinesfor recording biopotential measurements in the MRI environment.
Researchers can now easily add an olfactory element to expand general psychophysiology studies, enrich virtual and augmented environments, or examine how scent perception affects a variety of applications. BIOPAC’s new Scent Delivery System (SDS200-SYS), connects to an MP160 Research System with AcqKnowledge, and delivers up to eight scents to participants.
You Will Learn How To: • Add olfactory stimulation to any experiment • Optimize setup to get the best results • Combine different types of stimulation
BIOPAC provides software and hardware that allows research teams to study physiological measures related to stress. Here are a few notable studies using BIOPAC equipment for ECG, EDA, and EEG/ERP. Moms Moderating Stress Can relaxation techniques help lower stress on both mother and fetus? Using an MP36R Data Acquisition system to record ECG and EDA, this study […]
